Novel multifunctional aerosol inhalation device

The invention belongs to a novel multifunctional aerosol inhalation device, which consists of a mouth holder, a T-shaped joint, an extension tube, a liquid cup cover, a liquid cup and a gas connecting tube, wherein the T-shaped joint consists of a transverse tube and a vertical tube; and a liquid adding opening, a gas inlet opening, a one-way valve, an aerial fog generator, a hose and a sand ball. The novel multifunctional aerosol inhalation device can be used for aerosol inhalation, off-line breathing function training and off-line continuous airway humidification of an artificial airway patient and aerosol inhalation treatment of an ordinary patient. In the use process, the novel multifunctional aerosol inhalation device has the following advantages that aerosol inhalation liquid is sealed, so that the severe choking cough caused by reverse entering of the aerosol inhalation liquid into the airway of the patient due to the body position change of the patient cannot occur; the medicine waste can be avoided;
